Add UNC crossing option for FailSafe condition
Added a unc-failsafe meson option that if set to true, would then check
if any temperature sensor PIDs exceed their upper non-critical
threshold. If a sensor is detected to have exceeded their UNC, then the
zone associated with that PID would go to FailSafe.
By default, this option will be set to false for backwards
compatibility.
